新文章 DoEasy 函数库中的时间序列(第五十五部分)：指标集合类已发布：

本文继续开发指标对象类及其集合。 为每个指标对象创建其描述和正确的集合类，从而实现无错存储，并从集合列表中获取指标对象。

编译 EA 并在终端图表上启动它。
初始化之后，“智能系统”日志显示有关函数库的初始化消息。 两个创建的指标的参数，它们当中分别拥有完整和简洁参数列表：

--- Initializing the "DoEasy" library ---
Work only with the current symbol: "EURUSD"
Work with a predefined list of Periods:
"H1" "H4"
Symbol time series EURUSD: 
- Timeseries "EURUSD" H1: Required: 1000, Actual: 1000, Created: 1000, On server: 6350
- Timeseries "EURUSD" H4: Required: 1000, Actual: 1000, Created: 1000, On server: 6255
============= The beginning of the event parameter list: "Standard indicator" =============
Indicator status: Standard indicator
Indicator type: AMA
Indicator timeframe: H1
Indicator handle: 10
Indicator group: Trend indicator
------
Empty value for plotting, for which there is no drawing: EMPTY_VALUE
------
Indicator symbol: EURUSD
Indicator name: "Adaptive Moving Average"
Indicator shortname: "AMA(EURUSD,H1)"
--- Indicator parameters --- 
- Averaging period: 9
- Fast MA period: 2
- Slow MA period: 30
- Horizontal shift of the indicator: 0
- Price type or handle: CLOSE
================== End of the parameter list: "Standard indicator" ==================
 
============= The beginning of the event parameter list: "Standard indicator" =============
Indicator status: Standard indicator
Indicator type: AMA
Indicator timeframe: H1
Indicator handle: 11
Indicator group: Trend indicator

Empty value for plotting, for which there is no drawing: EMPTY_VALUE

Indicator symbol: EURUSD
Indicator name: "Adaptive Moving Average"
Indicator shortname: "AMA(EURUSD,H1)"
--- Indicator parameters --- 
- Averaging period: 10
- Fast MA period: 3
- Slow MA period: 32
- Horizontal shift of the indicator: 5
- Price type or handle: CLOSE
================== End of the parameter list: "Standard indicator" ==================
 
Standard indicator Adaptive Moving Average EURUSD H1 [10]
Standard indicator Adaptive Moving Average EURUSD H1 [11]
Library initialization time: 00:00:00.000

尽管指标类型只有一种 - AMA，但由于创建时指标参数不同，因此创建了该指标的两个句柄。 因此，这是两个不同的指标 - 每个都有其句柄。 两个指标对象分别创建，并将其放置在指标集合当中。
